What is the 413 Request Entity Too Large Error?

Error 413 Request Entity Too Large occurs when you try to access a web page or upload a file to the server – but the size of the data being sent exceeds the server limit. As a result, your request is rejected because the entity (data) you are trying to send is too large for the server to handle. Error 413 is from the family of HTTP 4XX status codes. They are those errors connected to the request made by the client.

Why Does Error 413 Request Entity Too Large Occur?

Several reasons could lead to encountering the 413 Request Entity Too Large error. The following points will help you clarify the possible reasons behind error 413.

File Size Limitations

Web servers typically set a limited size of data that can be uploaded or transmitted. This limitation ensures their efficiency and prevents them from becoming overloaded by large requests.

Server Configuration

The error might occur due to the server configuration settings. Administrators often set maximum upload sizes to prevent abuse or to optimize server performance. If your request surpasses these predefined limits – you will encounter the 413 Request Entity Too Large error.

Network Constraints

Sometimes, the error may not be due to server-side restrictions but could instead be network limitations. Slow internet connections or network congestion can interfere with the transmission of large data packets, leading to 413 errors.

Other Names of 413 Request Entity Too Large Error

The 413 Request Entity Too Large error has many different names, such as:

  • Status Code 413
  • Error 413
  • HTTP Error Code: 413
  • 413 Request Entity Too Large
  • 413 Payload Too Large
  • Entity Too Large 413
  • 413 Request Entity Too Big
  • HTTP Error 413

How to Fix the 413 Request Entity Too Large Error?

Encountering the error 413 Request Entity Too Large can be resolved through various methods & techniques. You can follow the below steps to fix error 413.

Check File Size

The first step is to verify the file size you are trying to upload or the data you are attempting to send. If the size exceeds the limit, reduce the file size and retry. If this does not work, try to send the large files via SFTP.

Sign in to your site through SFTP and look for the wp-content folder. Here will be the uploads folder. Put your file in this folder and then check.

Update Server Configuration

If you can access the server settings, consider adjusting the configuration to accommodate larger file sizes. This typically involves modifying parameters such as client_max_body_size in the server configuration files. However, be cautious when making these changes, as they may impact server performance & security.

Use Compression Techniques

Compression can help reduce the file sizes before transmitting them to the server. Utilize compression algorithms such as gzip or deflate to compress files before uploading them. This minimizes the risk of encountering the 413 Request Entity Too Large error and improves overall transfer efficiency.

Split Large Files

If you are dealing with large files that cannot be compressed sufficiently, consider splitting them into smaller segments. Uploading smaller chunks of data reduces the likelihood of encountering size limitations set by the server.

Optimize Network Connectivity

Ensure that your internet connection is stable and operating at an optimal speed. Slow or unreliable connections can contribute to the occurrence of the 413 Request Entity Too Large error. Also, try accessing the website or uploading the file using a different network or internet service provider in the first place. Because sometimes, it is nothing but just an internet issue.

Use Alternative Methods

If all else fails, consider alternative methods for transferring the data. This could involve using a different file-sharing service, transferring the files via FTP (File Transfer Protocol), or utilizing cloud storage solutions that are better equipped to handle large data volumes.

How to Manually Upload the File through FTP?

Install FTP Client: Download and install an FTP client.

Open Client: Launch the FTP client.

Report the Issue

If you believe the error is due to a server misconfiguration or network issue beyond your control, consider reporting the issue to the website or service provider. Provide information about the error and any relevant circumstances – that assist them in diagnosing & resolving the problem.
